I install the plugin using:
serverless plugin install --name serverless-mocha
when I try to create a function like this:
sls create function -f testFunction --handler src/functions/testFunction.testFunction -p src/tests/

I get the following result:

Serverless: Deprecation warning: CLI options definitions were upgraded with "type" property (which could be one of "string", "boolean", "multiple"). Below listed plugins do not predefine type for introduced options:
             - mochaPlugin for "function", "path", "handler", "httpEvent", "reporter", "reporter-options", "grep", "live", "root", "compilers", "timeout", "exit"
            Please report this issue in plugin issue tracker.
            Starting with next major release, this will be communicated with a thrown error.

     SDK Version:               4.2.2
     Components Version:        3.8.3

It creates the function file at src/functions/testFunction.testFunction.js but the serverless.yaml file changes are:

  undefined:
    handler: src/functions/testFunction.testFunction

and no test file is generated.

Hi,
Use the 1.83.0 serverless version.
npm install -g [email protected]
Best

It's Strange, but I managed to make it work by using --function instead of -f like this:

sls create function --function testFunction --handler src/functions/testFunction.testFunction -p src/tests/

Should be fixed with #151

@tdi this plugin seems to miss types for CLI options it defines, such functionality was at some point added with v2 of Serverless Framework, and is scheduled to be mandatory in v3. Is there any chance to have mentioned PR merged and published?
